+  (E4, pre-registered gate <= 6.26). Checkpoint rababa-checkpoints:/rababa_arabic_distill_small/run-007-r7-muon-6ep/best.
+  The two measured wins compound: 8.259 -> 4.8218 full-set windowed DER-CE (teacher

+  release at the same architecture and artifact size. Still misses the strict teacher+0.5pp
